To tI/Z whom, it may con/cern:

Beit known that I, ROBERT KLEIN, a subject of the King of Prussia, German Emperor, residing at Solingen, in the Province of the Rhine, Kingdom of Prussia, German E1npire, have invented certain new and useful Devices for Adjusting the Height of the Cut in Hair-Clipping Machines, of which the following is a specification. j

The present invention relates to a new, sim le, and reliable device for adjusting the heig t of the cut in hair-clipping machines, which device' possesses various advantages over the devices for this purpose which are already known. v

Referring to the accompanyingdrawings, Figure l shows a side view, and Fig. 2 a plan view, of the apparatus.

In the drawings the apparatus is shown attached to a clipper of the usual construction, comprising two blades b c, provided with cutting edges in the form of a comb and operated by meansof the handles a a. The lower blade cis connected, by means of a bolt d with the head e and milled nut firmly with the casing g. Through the ho low bolt d and the nut f there passes in the wellknown manner the set-screw o, which serves for the adjustment of the cutters. The new adjusting device consists of the comb k of usual form, provided with the side laps i, which swings on the hinge h and has the heel-piece Z, against which the spring n, ad'- justable by means of the nut m on the casing, is pressed.

The new device is used as follows: In order to obtain a greater height of cut,` (a greater length of the hair,) the set-screw o is screwed down. This causes the metal screw to push the comb 7c from the cutting-surface formed by the plane of contact of the two cutter-blades b c, overcoming the resistance of the spring n acting in the oplposed direction. In order to diminish the eight of cut, the set-screw is turnedin the opposite direction. This then draws back and the comb k follows it under the impulse of the spring n, pressed against the heel-piece l. On the side laps f1'. of the comb 7c there can be a scale The edge of one of the cutterblades may serve as the index-line, or this may be provided for in any other suitable way. By means of the disk, serving tosecure the hinge, and the screw m, serving to regulate the spring n, the spring-pressure can be varied and adjusted elastically if the part of the spring lying under the head of the screw be arched or curved..

The main advantage. of the above-described construction consists in the isimplicity of the adjustment of the cutter height, which itself during the slight cutting and against the slight resistance can be adjusted by means of the set-screw by theiingers of the hand holding the hair-clipper. This advantage is` particularly important when during the hair-cutting it 1s desired to increase gradually from a very small height of cut to a Greater one, so as to avoid Iclipping in steps. In all machines hitherto constructed this was impossible without removing the machine, as the adjustment was toodifiicult to be able to be accomplished without the aid of both hands. Moreover, it is extremely easy to cleanse the cutters and the comb of a machine constructed as above described, because for this purpose it sufiices to fold over the comb on the, hinge. Finally, the machine is considerably cheapened through the simplicity of its construction.

Having nowv particularly described my .said invention, I declare that what I claim is# 1.
